GENERALPROPERTIES TECHNICAL GUIDE01 Front CoverTensile testing reveals much about the mechanical PROPERTIES of Polyethylene products. Qenos manufactures and tests product samples in accordance with standards such as ASTM D638 and ASTM D882. Data collected includes tensile stress and tensile modulus, elongation at break as well as yield stress and strain. The resulting stress/strain curves are used by Qenos for product integrity, specifi cation development and product and process improvement , the Qenos brandmark, Alkathene, Alkatuff, Alkamax, Alkadyne and Alkatane are trade marks of Qenos Pty PROPERTIES1 GENERAL PROPERTIES2 Qenos Technical GuidesTABLE OF CONTENTSWHAT IS Polyethylene ?
